Did Delta serve turtle soup in int'l first class between
NYC and Frankfurt in the early 1990's?

I am in the process of coverting several boxes of old family
video from 8mm video to DVD video. One of the tapes was
videotaped when my family were flying from Frankfurt to
New York. There was no date on the tape. The only clues
are whatever were spoken on the tape. It was a first class
cabin in a two-row 2-1-2 configuration.(767?) My little
niece was sitting in the middle single seat as others family
members tried to convince to try the "turtle soup" during
lunch service.

Prior to landing in NYC, every first class passenger were
also given a $50 Tiffany's gift certificate. On the video,
a DL flight attendant was show handing me the certificate.
(a grandma-class FA, probably from Pan Am?)

Based on this, can anyone help me determine what month/
year, this video was shot?

Thanks!
